Customize context menu Nautilus or Nemo in Gnome 3 Ubuntu 18.04

I would like to customize the context menu on Desktop in Gnome 3. Tried it with Nautilus and also Nemo. In Nautilus I didn't found any solution yet, but in Nemo you can edit some actions. After installing Nemo I have added Active=false in all ".nemo_action" files, but this are not all actions from the context menu. I have edited them in the dir /usr/share/nemo/actions/

Is there any way to remove all items in the context menu for Nautilus or Nemo? Nautilus and Nemo are both fine to use as long as there is any way to customize is.
